小直径锚索在高地应力大变形隧道施工中应用（The small diameter anchor cable is applied in the construction of high ground stress deformation tunnel）

小直径锚索在高地应力大变形隧道施工中应用（The small diameter anchor cable is applied in the construction of high ground stress deformation tunnel） Statistical analysis of the mechanical management of the slope of the tunnel no.9 Giant scene only (wui coleopling, LTD.) 1. Project overview China is currently building the longest wu-coleopling tunnel (20050 meters) in the country, which is located between the redevelopment of the railway lanzhou railway line and the longditch station. Designed to be two single-wire tunnels with a line spacing of 40m. The maximum depth of the hole is 1,100 meters, and the design takes long tunneling measures, with 13 incline shafts and 14 auxiliary shafts in one shaft, of which 9 # slope is one of them. The slope of the wu-coleopling tunnel is located in the ridge section of the ridge, with a total length of 2429 meters and an average slope of 11.76%, with a maximum slope of 12.61%. Set eight lanes and five tunings. Inclined hole wall rock breakage and Ⅴ class accounts for over 50% of surrounding rock, the excavation area of 39 m2. The main area of the cave is a thousand rocks, and the area of the excavation area is 71.57-74.6 m2. As of June 30, 2005, the right line of zhengdong was completed by 1511 meters and the left line was completed 600 meters. The hole is accumulated into a hole of 1,660 meters. 2. Slope equipment configuration An average of 200 meters per month and 250 meters per month. The following table is configured in the slope equipment: The serial number Equipment category Device name specifications The Numbers one Earthwork machinery excavator DH220 1 m3 90 kw one 2 Earthwork machinery loader 2.7 m3 ZLC50C 154.5 KW 2 3 Earthwork machinery Tunnel loader ITC312H4 63 kw one 4 Earthwork machinery Axial flow fan MFA125P - SCHS 220 kw 2 5 Earthwork machinery Axial flow fan MFA100P - SCHS 110 kw one 6 Power machinery Electric air compressor P900E 25 m3 / min to 160 kw 3 7 Power machinery Electric air compressor P950E 25 m3 / min to 160 kw 2 8 Power
